AI Explanation
The correct answer is D) 80 degrees F. To determine the wet bulb temperature, we need to use the given dry bulb temperature (90 degrees F) and the relative humidity (65%). Using a psychrometric chart or a wet bulb temperature calculator, the wet bulb temperature corresponding to a dry bulb temperature of 90 degrees F and a relative humidity of 65% is approximately 80 degrees F. The other answer choices are incorrect because: A) 62 degrees F is too low for the given conditions. B) 63 degrees F is too low for the given conditions. C) 77 degrees F is slightly lower than the correct answer of 80 degrees F.
